EEA Daviz is a web tool developed by the European Environment Agency which
helps creating interactive data visualizations easily through the web
browser, no extra tools are necessary. It is free and open source.

You can generate attractive and interactive charts and combine them in a
dashboard with facets/filters which updates the charts simultaneously.
Data can be uploaded as CSV/TSV or you can specify SPARQL to query
online Linked open data servers (aka sparql endpoints).

It is simple to use, needs no desktop application, everything is done
through the web by uploading an “excel file”, CSV, TSV. You can also query
the “web of data” via public available sparql endpoints.
